Be it'known that I, Jonssc 'ins, Jr., a

particularly adapted for application t-oa dry battery, although thedevice may be used many connection in which is found applicable.

If an ordinary. binding post is me ely fastened to a dry battery, thepost will project outwardly from the side ofthebattery and when a numberof cellsare used in'conjunction,-the binding-post of one cell is liableto contact with that of anotherand ruin. the batteries.

The projecting posts are also aptto be broken ofl in packingand"inshipment.

I havefound that a substantially V-shaped retaining portion G, formingthe resistant .member fulfils the objects sought.

vMy p culiar construction is especially adaptedto the construction of a.dry battery,-s o that no part of the post projects outside of the outerperiphery of the cell'.- It is much. easier to manipulate of thefastening device,
